if you swap into an h22 into an SI, you have to have an ecu, but do you also need the transmission?

 

yo're gonna need a tranny in any car. i really dont understand your question, if you're asking if you need the tranny from that exact h22, then the answer is no. most or all h series tranny's shouold bolt up the the h series motor

 

go find a long block h22a u can get them for like 1200....keep your Si tranny will run fine with the vtec motor..i drove my friends for a couple hours a couple weeks ago...and i didn't notice one difference to my friends usdm vtec....all u gotta do is get the motor...swap it with the Si tranny and get a p13 ecu and your set

 

sweet, thanks, so all i need is the motor and ECU to run it? and of course run the vtec wires... would i be able to use my SI tach? and just know where it redlines? so.... if i buy an h22 and sell my h23, i could get do a swap for pretty cheap right?

 

an h22 and a si tranny will work but it will fall out of vtec during shifts.... i would get the h22 tranny also.

 

what do u mean fall out of vtec during shifts?

when at wot (with the h22 tranny) and shifting at redline. you can keep the rpms above 5000 rpms keeping vtec engaged. hes saying the si tranny won't stay above 5k, which will disengage vtec. ( i'm assuming this is what he meant)

 

that is what i mean, thinks for clearing it up for him 93preludevtec....

 

just to be sure....you guys are saying that a B-series Si trans. will bolt up and work with an H-series block? I've never heard of this and just wanted to be sure of what I am hearing. Quite interesting.

no, they are saying a prelude Si H-series trans will bolt up. you cant bolt a B to the H.

 

I was really starting to wonder about that. I knew there was no way to bolt a b-series to an H-series and this post was making no sense to me at all. For some odd reason I wasn't making the Prelude SI connection. Sorry, been around too many damn civic swaps lately.
